FORMULA

This sequence k(m) is associated with the array T(2,3,0) at A125150 as follows: row m consists of numbers of the form Floor[(2^p)/(3^k)] for k=k(m).

EXAMPLE

The pairs (j,k) for the first six rows are

(0,0), (5,2), (4,1), (9,4), (8,3), (13,6).

First term in row m is Floor[(2^j(m))/(3^k(m))],

so for m=1,2,3,4,5,6, the first 3 terms are

1=[(2^0)/(3^0)], 3=[(2^5)/(3^2)], 5=[(2^4)/(3^1)].

CROSSREFS
